Specification of ietters Patent.

Paten ed only 231, more,

To all whom it may concern: Be. it known that l, GLENN S, WILLIAM- son, acitize -of the United States,- and 1e siding in the borough ,of- Manhattan, county and State New 1 York, have invented oerta-in new and useful vImpro einents in Minting-Bresses, of which the, following is a specification.

This invention relates to-multiple rotary web printing-Presses, to improvements in mechanism for assembling the printed sheets in newspaper form,

The ohjeetof-the invention isto oilect a very great-reduction in the amountof Waste due to the tearing ofthze webs, to avoid the consequent serious loss of time, to reduce the labor; andattention incident to the running off-the press, and to improve theappearame ofthe product by remouingthe cause of the smu-tting of the pages. which is often observable.

In modernmultiplerotory web printing presses the slieetsmay helassembled entirely in book-fold, that is with all of the,longi-. tudinally-foldedsheets nested together, or the newspapers may bevformed of sections placed together, each sectioncomprising a plurality of sheets inbook-fold. For some purposes it is more desirable to book-fold, and for others it is moredesira ble-to form In general, it is Very desirable to have all of the sheets assembled in bookbecause this avoids possible subsequent loss of part of the paper; but this mode of assemblin has a very serious drawback, in

that it cal s for the utilization of numbersof a angle-bars. In book-folding as now practised in multiple rotary webpresses the double-width Webs are slit longitudinally,

and the course of the so-produoed smglewidth webs atone side must be changed so as to cause them to travel in superposedsremovable bars longitudinal e ges of the sinle-width webs,

lation to the others. The singlerwidth webs are thus brought all together, so thatthey may" be passed over a longitudinal folder tobenested'togother in book-fold; but the changing of the nourses of the halves of the webs atone-side necessitates the use of'a number otanglediars, two for each sheetso transposed. As is wellrknown, these are innositionod at anlangle tot-he over which the-webs must drawnvwith considerable strain and friction. From-the very nature or things these angle-bars are constant seats of trouble. Should I the elit+ and more particularly.

' this sheet, but in all the other.

this the hook-folded pr terfi hemmedull, orif-for any other reason the-edges. oft-the slit Wehsare rough,one or, more of the. webs. will tear across at the anglesbar; and weak spots or slime marks in 4 paperwill, produce the same result. Theltearingnf a web necessitates, ofcourse, the stopping of the press. It. also necessitates- .the tearing: away-.- of the afiected Web and the i 's-threading oil the paper. It is often necessary, also',to tear away anumber of the wehsahoweorhelowtheweh affected;

and, in any event themater-ial of all the webs beyond the negionof a break in one of them is waste because could only produce hicornplete papers. lln additiontothis the broken sheetmay have to be torndiagonally, or feathered, for many feet in rein of the break, in. order to thread it through the pross'agein, and this is. Waste-not only in sheets, because their corresponding parts must he discarded asineomplete papers. The whole operation, involves. the Waste of a large ,omotmt of material anda serious. lossof time. Becauselthe consequencesot the tearing of it Web stlan angleshar are not limited to that. W alone, thetotal waste due to angle=barsumountsto a largesum and is very costly to the printing plant, Moreover, thennglonhorsoarelilrely to spoil the appearanceofpeinteel wehs-hy-smea-ring of the comparatively-trash ink,- loecanse asthe webs pass overthe the. latter collect more or loss; of the ni-thesurtaoes and redistribute 1 over. .-.the= ding portions otthe-wehs.

ln anoordonoe with. away with angle-bars; Ioine a plurality of-seats. of, pnintingcouples for printing a plurality ot- Webs, and two longitudinal folders. in series, with slitting nlechanism, and with means forassoaiating and leading all'the wehs to the firstlongi-tudinal folder, whens-the. two itudinal halves, of all the douhlouwidth slnro folded or doubled over on each other, a t r which-the assemhlage of we oondneted over'the sooondtormer, where they are again .tolded lo itndinally. After not isfolded and out transversely anddelivored by suitable my invention 1. do

Pretorahly a single. slitting r former, and compensating means is interposed between the slitting means and the first former for causing the heads of pages on the two longitudinal halves of the slit webs to come intofront register, it being customary to print the pages of the two halves in staggered relatlon Forwarding mechanism is provided between the two longitudinal folders. The first longitudinal folder with its former is double-width; the second longitudinal folder is preferably smaller, being single-width. Thus, I superimpose and simultaneously fold or double over the plurality of webs upon each other longitudinally, slitting them at an appropriate point or.points, and then again fold the so-produced assemblage of superimposed single-width webs longitudinally to produce the book-fold. The double-width webs are slit longitudinally, the single-width webs are then compensated, next the slit webs, still traveling double-width, are superimposed and folded over upon each other longitudinally, after which the assemblage of superimposed single-width webs are folded longitudinally.

A further object of the invention is to enable-the press either to book-fold its entire product or to associate it in sections to be gathered together, by means of a plurality of longitudinal folders and without the use of angle-bars. In the preferred construction I provide means for changing the relative position of the twov folder's'already referred to so that the second folder may receive one longitudinal half of the webs direct, instead of receiving all of the half webs in superimposed condition from the 5 led to the printing couples and the. printing isefiected in the usual-or any approved j manner.

rative position to large folder. -i'Preferably, the second folder is rotatably mounted or swiveled 'so that it may be turned through an arc of approximately 90, from one o the other. In one osltion it is at right angles to the-large ormer so as to operate in series therewith. In the other position it is in line with the direct run of one longitudinal half of the webs. In the embodiment of the invention illustrated, I employ three longitudinal folders, a large ordouble-width longitudinal folder in front of l V gitudinally. Preferably, thewebs are slit and central with respect to the other two longitudinal folders. Of these two longitudinal folders the one is rotatably-mounted, so that it may be positioned either in series with the large longitudinal folder or in parallel relation to the third folder. In the first instance the mechanism is arranged for. book-folding. In the second instance the two longitudinal halves of the webs, after slitting, run direct over the two parallel folders,so that the sheets are assembled 3 in sections, which sections, placed side by side, complete" the newspaper.

In the accompanying drawings illustrating the invention by means of the preferred idea ist embodiment thereof: Figure 1 is a rear elevation, parts being broken away, of an assembling mechanism embodying my invention, the same being shown as arranged for book-folding; Fig. 2 is a side elevation of the rear part of a printing press with the assembling mechanism, parts being in' sectionand broken away; Fig. 3 is a plan view, parts being broken away; Fi ,4 is a side elevation, with parts in section and-.-

broken away, showing the mechanism shifted for assembling the papers in sections; Fig. 5 is a sectional plan view, with parts broken away and in section, corresponding to Fig. 4:; Fig. 6 is a rear view corresponding to Figs. 4 and 5, parts being broken away; and Fig. 7 is a detail view. The

any suitable form and arrangement, .and

the printing mechanism is, therefore, not illustrated 1n detail.

I have indicated a sextuple press, for purposes of-illustration,

there being three sets of printing couples.

. Each set is shown as comprising two couples, each couple consisting of a'plate or printingcylinder P and an impression cyl- -inder I. As is usual, the plates on each plate cylinder are in staggered relation.

The double-width webs, a, b, 0,

ing shown for purposes of illustration) are Fig. 2 indicates the great saving in floor (three bespace that may be efi'ected by my invention,

' by the shortening ofthe press,"asth e printing couples can be located as near the rear end of the press as may be desired, all the ispace formerly devoted to angle-bars-being unnecessary. s

The plurality of double-width webs, either before or after printing, are slit lonsimultaneously and at one point, after printing, by means of a slngle slit-ter. The slitter 10 may be located at any suitablepoint,

'- but I attain certain advantages by mounting it on the rear end of the frame A. The

full-width webs a, b, 0, are slit by being passed together'between the slitt-er 10 "and theroller 11. The slit-ter 10 may be either. driven or idle, and its pressure may be reg ulated by means of a screwvl2 acting-on a spring in the usual "manner. I provide means for compensatingfor the staggered relation of the printed pages on the two longitudinal halves of the slit webs. I premenace fer to locate this means at a suitable point between the slitting means and the first longitudinal folder Forthe purpose of illustration I have shown a roller 13 carried 5 by an arm 14 pivoted on the frame A, whichmay be adjusted by means of a screw 15. One-half of the webs passes around: the roller 13, which is adjusted as the circum stances may require. Figs; 2 and 3 show the compensator acting on one longitudinal half of all the webs.

At the top of the assembling mechanism is a double-width longitudinal folder F. The 1 same comprisesa triangular former or internal guide 16 and external turners or rollon; 17 at the point thereof. Theformer is of any suitable or approved construction. At its top is a forwarding roller 18 with which cooperate trolle s 19; and below the rollers 17 is a pair gripping-rollers 20.. The folder F is centrally in line with the direct run of the webs; by which I mean that the webs reach thetop of the former 16 5 without lateral transportation.

\ Means, the specific character of which maybe varied, are provided forassociating and leading all of the plurality of webs from the plurality of sets of printing couples to the first longitudinal folder F. In the particular construction illustrated, the doublewidth webs as, b, 0 pass separately from their printing couple over adjustable register rollers (Z, c, f, and thence pass together over the roller 11 and beneath the slitter The single-width webs are then compensated as described,-and the slit webs, still traveling double-width, are led together between the forwarding-roll 18 and the cooperating'trolleys 19 p 4 Beyond the longitudinal folder F are two other longitudinal folders F and F these folders being preferably of single width and arranged at opposite sides of the cen' ter line of the folder F. The folder F comprises a triangular former 16 and external turners 17 in addition to which I have illustrated the gripping or fold-layin rollsis Between the longitudinal olders I* and F I provide forwarding means, the same being shown as comprising a driven forwardin -roller 18 and trolleys 19-, at the top 0 the folder F In like manner the longitudinal folder I? has an internal guide or former 16 the external turners 17", and the fold-laying rollers 20;"; and a forwarding-roller 18 and trolleys 19 'are located at the top of its former.

One or' both of the longitudinal folders J I, F is movable between two positions, as will be presently described. Preferablmthe longitudinal folder I is alone so movable, the longitudinal folder F being fixed in position in line cwith the direct run of one longitudinal half of the webs. The other 1 longitudinal folder F may be positioned either in line with the direct run of the other longitudinal half of the webs, that is to say, in parallel relation to the longitudinal folder F or in series relation to the double-width folder F. In Figs. 1, 2 and I 3, the longitudinal folder F is shown in series with the longitudinal folder F; in Figs. 4, 5- and 6 it is shown in parallel with the ,longitudinal' folder F Between the two longitudinal folders F and F compensat- Zing means is provided, for insuring that, when these longitudinal folders are in parallel relation, as shown in Figs. 4, 5 and 6, iand the product of one side is led across to ithe other to be transversely folded and out therewith, the pages of the two sections will be substantially in registry, so'that the eut- Eting knives will always operate in the itransverse unprintedv strips between pages. i For this purpose I have illustrated a roller 95,. caried by an'arm 96 pivoted to the frame A and adapted to be ad'usted by a screw 97. lhe longitudinal fol. or F is preferably g mounted rotatably,'so as to turn through an iarc of 90. To this end I have shown the so frame or supporting structure A for the flongitudinal folder F swiveled on a substantially-central' vertical pivot P." Suth- -cicntclearance is provided between the 1 frame A. and the parts carried thefeb and the-frame pairtA of the longitudinal older F and the parts carried thereby, to permit of the rotation of the left-hand longitudinal folder. As convenient means for effecting the turning of the longitudinal folder F 100 I have shown a stationary arcuate rack 30, with which engages a pinion 31 (see Fig. 2) on the lower end of a. shaft 32 journaled in the frame A a handle crank 33 being provided at the upper end of the shaft and connected therewith by bevel gears 34.; or any other suitable means may be employed. The forwarding mechanism, shownas comprising the forwarding-roler 18 and the trolleys 19' are mounted to turn with the v1 .10 longitudinal folder F. In the. particular construction illustrated, the roller has a journal extension at one end received in a bearing 90 on lthe swiveled frame, andto.

Ward'the other end isprovided with an an- 'nular groove which isreceived in a1 bearing 9i on the same frame. The trolleys 19 are carried by arms pivoted on a shaft 92 car ,ried' by brackets 93,94 on this'frame. As

is usual, these and all the other trolleys are preferably provided withadjustable spring pressure devices. i

The swiveled frame. part A also carries: transverse folding and cutting mechanism and delivery devices, which may be of any 12 -ers 3Z between which the papers are forced 139 by any suitable form of tucking blades carried by the folding cylinder, a rotary fly 39, and delivery tapes 40. Such devices are so well-known to those skilled in the art that further description here is unnecessary. In Fig. 2 the fly 39and tapes 40 are shown arranged to deliver into the passage-way between thepress-frame and the associating mechanism, but it will be obvious that they may be arranged to deliver in the opposite direction if desired. In like manner, similar parts are provided in conjunction with the longitudinal folder F there being a cutting cylinder a folding cylinder 36, folding rollers 37*, a fly 39 and delivery tapes 40 In accordance with the invention means are provided for driving the rotary parts carried by the frame B in either of its two positions. Such means may be widely varied; and, in fact, the various arrangements of gearing shown throughout are merely for the purpose of indicating the existence of driving connections, the particular arrangement of which is onlya matter of mechanical skill.

41 indicates a shaft which may be regarded as the main driving shaft. It carries a bevel gear 42 which meshes with another bevel gear 43, the latter being mounted on a shaft 44, which carries a gear 45. A train of gears 47 mounted on the frame A is driven from this gear 45. On the shaft 48 of the topmost gear of the train is a bevel gear 49, which. meshes with another bevel gear 50 on the end of the journal extension of the forwarding-roller 18 of the longitudinal folder F The trolleys cooperating therewith may or may not be driven, and the same applies to all the trolleys employed. The lowermost gear 47 of the train 47 is a slip-gear, being capable of longitudinal movement of the shaft to. disengage from the gear 45; as is indicated by dotted lines in Fig. 1. This permits the longitudinal folder F to be swung around to the position shown in Figs. 4, 5 and 6, wherethe gear 47 meshes with a gear 51 mounted on the main driving shaft 41. The,

cutting cylinder 35 is shown as being'driven by means of a gear on its shaft meshing wit-h a gear 47 of the train 47';- and thefolding cylinder 36 is shown cared to the cutting cylinder 35. The folding rollers 37 are preferably geared together and one of them may be geared to the fly 39 by iiieans of an intermediate gear. The drivlng connections. for the fly 39 and the tapes 40 may consist of two gears 52, one of which meshes with the'gear 47, while the other meshes with a gear onthe shaft of the fly and a pinion on one of the shafts of the delivery tapes. The fold-laying rollers 20 may be geared together and may be driven from the folding cylinder 36' by means of a gear 53. As has been observed, the gearing may be rearranged in any suitable way. i

The gearing for driving the rotary parts carried by the frame portion A the same including the forwarding-roller 18 and fold-laying rollers 20 of the folder F, the cutting cylinder 35*, the folding cylinder 36, the folding rollers 37*, the fly 39 and the delivery tapes 40", may be similar to that shown in connection with the parts carried by the frame portion A or any suitable form of gearing may be employed. Gear connections, somewhat different from those described in connection with the parts at the left-hand side of the machine are illustrated, but are not described, because longitudinal folders I? and F are in parallel relation, as shown in Figs. 4, 5 and 6.

The forwarding-roller 18 is illustrated as mounted in bearings 90 and 91 similar to the bearings 90 and 91 of the roller 18. The bearings 91 and 91 are so formed as to be no higher than the rollers 18 and 18", so as to offer no obstacle to the passage of the webs thereover. Trolleys 19 are provided in conjunction with the roller 18*, and are in alinement with the trolleys '19 in this position of the arts. They are shown as similarly carrie by arms mounted on a shaft 92 mounted in brackets. 93%, 94.

buitable clearance is provided between the; rollers 18 and 18 with their bearings and between the trolley shafts 92 and 92* with their brackets, so as to permit the swiveled structure including the longitudinal folder F to turn. When the longitudinal folders F and F are acting together in parallelto turn out sections to be assembled side by side to form the newspaper, I refer to effect the longitudinal slitting of the webs at the rollers 18 andl8l, which then act'like one roller. To this end I have provided the adjustably-sprin pressed slitter 192, whichmay be either viven or not,--as preferred, the-same being shown for purpose of illustration as mounted on an arm carried by the trolley shaft 92 and cooperating with a groove in the extension of theforwarding- "roller 18*" tothe right of thebearing 91.

This slitter is preferablymounted" centrally of one-of the trolleys 19 (see Fig. 7). When the xlon 'tudinal folders F and F are in paralle the forwarding-rollers 18 and 18 may obviously either be. coupled together so that 18 is rotated by1 8, or

driving means may be provided for each f roller. For purposes of illustration 1 have 10 is driven by a bevel gear 107 on a shaft 62,-

hereinafter referred to. It will be understood that the driving connections for the two rollers 18 and 18 will be so propor tioned that these" rollers will be driven in synchronism. v

The forwarding-roller 1 8 and the gripping-rollers of the double-width folder F may be driven in the following manner: bevel gear 57 mounted on the shaft 41- meshes with a bevel gear 58 on a transverse shaft 59 which extends across thema'chiner Ait the opposite end of this shaft 59 is a bevel gear 60, which meshes with a bevel gear 61 on the lower end of an upright shaft 62'. At the upper end of the shaft 62 is a" bevel gear 63 which meshes with a bevel" gear .64 on a horizontal shaft 65 and this horizontal shaft 65 has a gear 66, which meshes with a pinion 67 on the journal extension of the forwarding-roller 18. The horizontal" shaft 65' extends inward! to the center line of the machine and is provided at its inner end with a bevel gear 68 which meshes with a bevel gear 69 on the upper end of vertical shaft 76, the lower end .of which is providedwith a bevel gear 71 meshing with a' bevel gear 72' on the end of one of the gripping-rollers 20 the two gripping-rollersbeing geared toget er.

In operation, for book-folding, the longitudinal folder F is positioned and the web's coming 'from the several sets of print- I ing 00 les are threaded as" shown in Figs. 1

suitable point,

he webs are slit centrally at any as by means of the shelter 10 The webs pass over the former 16 and the severed longitudinal halves are folded or doubled over between the pairs of rollers 1? and 20'. The superimposed halfwebs now pass over the former 1136 and: are folded .be'-' tween the turners 17f and the fold laydng rollers 20; after which the sheets, now in book-fold, are folded transversely,- eut', and delivered in any usual or approved manne'r, ashy means of mechanism such as illustrated for the purpose. In order to assemble the sheets in sections to be placed side by side to' form the newspaper, the longitudinal folder F is swung throu h an arc of 90 50' as to be positioned as s own in Figs 4 and' 5.

The slit webs are now brought down in the of the two longitudinial folders F and F now operating in parallel. The slitter 10 is preferably placed out of operation, as by being held up; and the compensating roller 13 is also preferably not now in use. The webs are slit by the slitte'r 102,- and the singlewidth web's pass half over the former l6 and half over the former 16F. and then between the r llers- 17*" and 20 and 17 and 20 The two longitudinal folded sections thus formed may be collected in any ap proved manner. Fig. 6 shows the product from the longitudinal folder F carried transversely across, by way of the compeirsator 95, between the" rollers 20* with the product from the longitudinal folder F the combined prodnet being then transversely folded and cut and delivered by the transverse folding and cuttiilg" mechanism and delivery beneath said longitudinal folder F In like r'nanner,- the' product from the lon=gi-- tudinal folder" F may be led across to the other side,- and the sections transversely folded and out and delivered at the righthand side of the machine.

VVhile I have shown two complete transverse folding and cutting and delivery'mecha'n isms, in conjunction with the two longitudinal folders I? and F it will be obvious that these parts shown in conjunction with the longitudinal folder F may be omitted,

the cutting cylinder 35, folding cylinder 36',

ing used both forboolt-fold'ing and for oper'-;

ating on collected seetions, as shown. Or, if two complete mechanisms of this character are used, as illustrated, the parts 35, 36-, 37, 39 and de need not be mounted so as to turn with the longitudinal folder F since the corresponding parts at the right of the machine' may be used exclusively when' the longitudinal folders F and F are operating in arallel. v

have shown a guide roller 1'10, carried by pivoted arms or hangers 111. which may be swung down below the rollers '20. as shown in Fig. 1, when the longi'ttulinal fold ers F and F are at right angles to each other and-acting in'series; This roller may beswung' up out or the way when the longitudlnal folders F and F are in parallel (see Fig. 7); This roller may, however,- be dispensed with. v

While I- have shown and partici-l l'arl'y described one embodiment of my invention, it will be understood that many other embodiments are possible and that many changes may be made without departing from the scope of the invention.
